Answer:

x =22

Step-by-step explanation:

ABCD is a parallelogram. In parallelogram, adjacent angles are supplementary.

∠B +∠C = 180

4x + 12 + 3x + 14 = 180

Combine like terms

4x +3x + 12+ 14 = 180

  7x +  26 = 180    {Subtract 26 from both sides}

           7x = 180 -  26

           7x = 154      {Divide both sides by 7}

             x = 154/7

x = 22

Anastaziya [24]

Answer:

a = (r/x) -b

x = -14

Step-by-step explanation:

r=x(a+b)

Divide each side by x

r/x = a+b

Subtract b

r/x  -b = a

x/2=-7

Multiply each side by 2

x/2*2 = -7*2

x = -14
